Simple game to solve a "jigsaw" puzzle.
You can select any image file as your jigsaw.
The picture is divided into some number of rectangular pieces, which can then be progressively swapped into place to recreate the original picture.
User controls set the number of pieces (difficulty level), whether or not swaps happen with animation, etc.
At any time you can view the original picture as an assist.
It tracks the number of moves and the time taken to solve the puzzle.
